Lady Gaga marked the release of her record 'Artpop' with - what else? - a pop-up shop and exhibit on bustling Cahuenga Boulevard in Hollywood. Face painting, video game dancing, photo booths and a display of her wackiest outfits provided eye candy for free, while little monsters with money in tow walked away with t-shirts and of course, the new CD. The pop-up continues through November 12 at 9 p.m.
